2 Claims. (Cl. 233-21) My present invention relates to an improved centrifugal separator of the type designed to separate liquid and solid matter in suspension, according to the specific gravity thereof and comprises a rotary cylinder into which that mattei` to be separated is fed, transverse fins for feeding the matter, and unique separating structure to receive and distribute the solid and liquid matter according to the layers of matter of different specific gravity.

The device of my invention may be used to separate liquid and solid matter and specic reference to such substances is deemed unnecessary.

In'the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised, but it will be understood that various changes and alterations may be made in the exemplied structure within the scope of the appended claims.

In the drawings;

Fig. 1 is a vertical sectional View of the separator of my invention.

- Fig. 2 is a horizontal sectional View at line 2 2 of Fig. 1.

Fig. 3 is a horizontal sectional View at line 3-3 of Fig. 1.

Fig. 4 is a horizontal sectional View at line 4-4 of Fig. 1.

Fig. 5 is a detail View of the slotted dispensing housings.

Referring now to the drawings wherein I have illustrated the present preferred embodiment of my invention I utilize a base 2 ported at 4 to supportI the casing or housing 6 on base 8 having a flange ring I0 secured by bolts I2. The base 8 is bored at I4 and has a rigid collar I6 to receive the bearing race I8 for balls 20.

Journaled in the bearing is a tube 22 having a collar 24- on bottom 26 of cylinder 28. Fixed radially within the cylinder, I employ the ns 370 which agitate and stir the matter to be separated which is injected through nozzle 32 of tube 34 supported on bracket 36.

Above the ns, the cylinder wall flares outwardly at 38 in conical formation and the rib 40 is threaded to receive the cap 42 confining gasket 44. This cap is also conical in formation and extends inwardly to the vertical wall 46 which has an upper closure wall 48 and its shaft 50 journaled in bearing 52 in the recess 54 of the upper casing section 56 secured at 58. A pulley 60 on the shaft 50 may be driven by a belt, not shown, to rotate the cap and the cylinder.

The cap 42 is provided wtih spaced series of slot 62 which are comp-artmented by partitions 64, 66 and 68. Exteriorly of the cap, the pairs of ribs 10, l2 and I4 direct the separated matter into the downwardly inclined chambers 16, 18 and 80 each having a spout 82, 84 and 86 communicating through ports S8, and 92 with the chambers.

The upper partition64 has threadedly engaging the same, a cylinder 94 formed with a flaring open dome 96, and the middle partition 66 has threadedly engaging it a concentric cylinder 98 having a flaring dome |00 with outer peripheral rib |02 to receive the conical bottom |64 open at |06.

From the above description it will be apparent that as the matter to be separated is fed to the interiorly finned cylinder 28 the matter will be rotated reaching the cylinder Wall speed quickly and then moving upwardly and will have formed definite stratum of matters of different specific gravity, the heavier, outside and the lighter inside. The outer strata will flow over the outward flare 38 and between Walls 42 and |00 to compartment 80 and spout 86.

The lighter stratum will ow upwardly from the cylinder 28 through opening |06 and the heavier of the two stratum will flow over Wall |04 and between walls and |00 to compartment 'I8 and spout 84, while the lighter of the two stratum will flow upwardly through cylinder 94 and between Walls 64 and 48 to chamber 'I6 and spout 82.

Obviously the separator may be adjusted as desired to separate the matter into two rather than three layers and the device will prove ecient in quickly and cleanly separating by centrifugal action such matter as may be fed therein.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is;

1. In a centrifugal separator, a hollow housing provided with a plurality of spaced spouts for the discharge therethrough oi separated mattei', a cylinder arranged in spaced relation within said housing, the upper portion of said cylinder flaring outwardly, a cap arranged in threaded engagement with the upper end of said cylinder, a vertically disposed wall projecting upwardly from said cap, a plurality of spaced horizontally disposed partitions projecting inwardly from said vertically disposed wall and secured thereto, there being a slot positioned between each pair of partitions for egress therethrough of separated matter, and means embodying a plurality of inclined chambers for conveying the separated matter from said slots to the ccmplemental spout.

2. In a centrifugal separator, a base provided with a central port, a hollow housing provided with a plurality of spaced spouts for the discharge therethrough of separated matter supported on said base, a flange projecting from said housing and secured to said base, a cylinder arranged in spaced parallel relation Within said housing, a collar projecting upwardly from said base, a bearing race arranged in said collar, the upper portion of said cylinder aring outwardly, a tube projecting from the bottom of said cylinder through said port, a cap arranged in threaded j@ Number engagement with the upper end of said cylinder, a plurality of vertically disposed fins arranged in said cylinder, a vertically disposed wall projecting upwardly from said cap, a shaft projecting upwardly from said cap and through said housing, a pulley mounted on said shaft, a plurality of spaced horizontally disposed partitions project` ing inwardly from said vertically disposed Wall and secured thereto, there being a slot positioned between each pair of partitions for the egress therethrough of separated matter, said slots being arranged one above the other in said vertically disposed wall chambers for conveying the separated matter from said slots to the complemental spouts, and spaced parallel ribs for direct- REFERENCES CITED The following references are of record in the le of this patent:
